I am using the wiznet6100 in macraw mode with the lwip ip stack. Currently i have the mac filtering turned off in socket0. (my initialisation code)
I am able to communicate over tcp, server up web pages, get an ip address via dhcp etc.
Now, if i turn on mac filtering (as part of my initialisation code) like this
I am able to get an ip address through dhcp and wireshark shows ARP announcements being broadcast…BUT i am unable to communicate with the server anymore. It is as though the mac filtering is filtering out everything except broadcast packets
Does anyone have any ideas as to what i may be doing wrong?
